SEWING-MACHINE PIPING AND BINDING GUIDE.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed August 27, 1913. Serial No. 786,895.

To all whom it may concern Be it known that I, Honnn'r M. GImIsT, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented or discovered certain new and useful Improvements in Sewing-Machine Piping and Binding Guides, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in sewing machine binders whereby a piece of cloth to which a folded binding strip is to be applied may be guided in such relation to the folded binding that the latter may embrace and cover both sides of the edge of the piece of cloth, or whereby the cloth may be so guided in such relation to the folded strip that the latter may be sewed to one side of the piece of cloth, and may project bevond the .edge thereof so as to form an edging or piping. In other words, the present invention adapts a sewing machine binder for use in doing either piping or edging work or ordinary binding, as may be desired.

The improvement consists in providing a guide for a piece of cloth which may have either a selvage or a folded edge, said guide being preferably arranged below the fold ing or binding guide, so that when piping or edging is to be done a piece of cloth to which a folded strip is to be sewed, to form piping or edging, will be guided to the needle of a sewing machine beneath the folded strip passing through the folding or binding guide.

In the accompanying drawings Figure 1 is a perspective view illustrating the operation of the improved binder in attaching a folded strip to the upper side of the edge of a piece of cloth, to form an edging or piping. Fig. 2 is a plan view of the improved binder, andFig. 3 is a side view thereof.

The present invention is shown as being applied to the form of binder shown in the Greist U. S. Patent No. 665,521, dated Jan. 8, 1901.

In the drawing, 12 denotes a presserfoot portion provided with a shank 13 by which it may be secured to the presser-bar of the sewing machine. Riveted or otherwise permanently secured to the presserfoot 12 is a supporting plate 1%.! to which is attached, by soldering or otherwise, a binder 15 comprising tapering scroll-formed upper and lower folding members between which is an open space for the reception of the edge of a piece of cloth to which a folded binding strip is to be attached when ordinary binding is being done, the cloth in such instance being supported by the raised platform or inclined work-supporting table 16 formed integral with a forward extension of the plate 14. Thus in using the device as a hinder the edge of the piece of cloth to which the binding is to be attached is inserted in said open space between the said folding members and is guided by the web of metal connecting said members. 1

Attached to the plate 14 is a spring arm 17 provided with a guide 18 for the folded edge of the binding, said guide serving to prevent the work from running out of place to the right should any considerable pressure in that direction be exerted thereon.

The plate 14 is provided at its forward end, or the end thereof nearest the operator, with a guide slot 19 open toward the left and the wall at the inner or right hand end of which slot serves as a guide for the edge of a piece of material which may thus be entered and guided beneath the folding or binding guide 15. This construction permits a piece of material, as 20, to be guided in such relation to the needle 21 of a sewing machine that a strip, as 22, may be folded upon itself, with its raw edges iii-turned, thus making practically a four-fold strip which may be guided to the needle in such relation to the edge of the piece of cloth or material 90 that the folded strip will be attached to the upper side of the said piece of cloth or material 20, and in such relation to the edge 23 of the said piece of cloth or material that the edge 24 of said folded strip will project beyond the said edge 23 of the material 20 in such a manner as to form an edging or piping. This result is due to the fact that the closed inner end or edge-guiding wall of the guide slot 19, which is open to the left, is out of line, in the direction of the feed of the work to the needle 21, with the right hand or guiding edge of the folding binder 15, being to the left of said right band edge of the binder, so that as the edging or piping strip is folded the folded edge 24:" thereof will project beyond the edge 23 of the material to which the said strip is to be sewed.

From the foregoing it will be understood that this improvement adapts an ordinary binder for use as a piping folder and guide, so thata piping strip, as 22, cut on the bias, may be folded and guided to the needle of a sewing machine in such relation to the cloth or material 20 as to form an edging or piping, if said cloth or material 20 be assed through the guide slot .19; or if it e desired to apply the folded strip 22 to the edge of the piece of cloth of material 20 in such a manner that said folded strip will embrace the edge of the said piece of material 20, to form a binding, the said piece.

of material 20 will be supported on the platform 16 and will be guided to the needle in 20 ing a piece of material to the needle of the machine together with a folded strip pass ing through the foiding guide, the

guiding edge of said guide for the piece of upper and lower scroll-formed folding and guiding members, said folding guide having an open cloth guiding space between said members, said supporting plate being provided, beneath said folding guide, with a guiding slot, which is open to the left, and the inner or guiding end of which is to the left, in the line of the feed of the work, of the 65 right or fold-guiding edge of the said folding guide; whereby, when piping is to be done, a folded piping strip, with its folded edge projecting beyond the edge of a guided piece of material to which said piping strip is to be attached, may be directed to the needle of a sewing machine.

in testimony whereof I aflix my signature, in presence of two witnesses.
